Project: Rotational Motion Portfolio

Question 1.

How does the movement of the earth affects the distribution of solar energy in the earth's surface?


These two phenomena of circulation of the earth and the earth's rotation on its 
axis is the variation of solar influence on the earth surface. he earth's rotation 
axis tilt of the angle 231 / 2 degrees is causing the phenomenon of day and 
night occur. Earth takes 24 hours to make one complete rotation. The Earth 
rotates west to east. The surface of the earth facing the sun during the day and 
would have received a lot of solar energy distribution compared with that
 experienced on earth during the night.

                            Question 2.

How rotation engine work?

Rotation engine is a type of internal combustion engines that use design to change
 the rotation of the pressure of combustion air-fuelmixture directly to the rotational motion,
 unlike ordinary piston engine which produces a reciprocating motion before
 being transferred to the rotational movement of the crankshaft. In the four-stroke cycle
 engine generated in the space between the housing shaped like oval epitrokoid
 the triangular rotor. This design produces a smooth high-rpm power from a compact
 and lightweight engine.
